Porsche says the new 911 Cabriolet is more torsionally rigid than before, and will offer the company's PASM active suspension system for the first time.

"The springs used for this are harder and shorter, the front and rear anti-roll-bars are more rigid, and the chassis overall has been lowered by ten millimetres. These adjustments give the 911 a more neutral feel on the road, with better weight distribution," the company says in its press release.

Like the 911 coupe, the drop-top version is wider than before, with rear-wheel drive models getting the same wider bodywork as all-wheel drive versions.

Standard 20-inch front and 21-inch rear wheels fill the extended arches, while a wider retractable spoiler and LED light bar that spans the width of the rear complete the look.

Additionally, the entire body is now made from aluminium bar the "front and rear sections".

Both the Carrera S and 4S are powered by a 3.0-litre turbocharged flat six 'boxer' engine, making 331kW at 6500rpm and 530Nm between 2300 and 5000rpm. Porsche claims 0-100 takes just 3.9 seconds in the Carrera S, and 3.8 seconds in the all-wheel-driven 4S – opting for the Sports Chrono Package shaves 0.2 seconds off both times.

Top speed is rated at 306km/h for the Carrera S, and 304km/h for the 4S.

As per the coupe, the 911 Cabriolet picks up a redesigned interior with the latest in driver assistance and infotainment technologies.

Sitting proudly in the centre of the dashboard is a 10.9-inch Porsche Communication Management infotainment unit, while two freeform displays flank the central, analogue rev counter.

The convertible comes as standard with a rear-view camera and park assist system, with night vision, adaptive cruise control and reversible occupant detection available as options.
